Space Weathering is described as the type of weathering that occurs to any object exposed to the harsh environment of outer space. Unlike on Earth, a man-made vessel wouldn't be affected by rain or wind. But the constant flux of high energy particles and micrometeorites.
Over time, Space Weather might darken man-made materials. But the article describes melting and vapor as well.
What would this look like over time? I assume painted surfaces would show the same weathering. Are there any examples of man-made devices where we've actually seen space weathering?
